Abstract

The need for new plants is needed to balance the demand for high electricity. To anticipate this, it is necessary to accelerate the achievement of the level of utilization of new and renewable energy (EBT) in the energy mix for electricity supply by encouraging the use of energy from water, biomass, solar, wind to electricity. The Biomass Power Plant (PLTBm) is one of the environmentally friendly alternative power plants that produce electricity and heat by burning biomass in boilers in this case from wood waste from furniture and old rubber trees. The Interconnection System will be implemented in this PLTBm, where interconnection with the existing 20 kV system will be carried out. Research carried out includes power flow, voltage drop, losses, and short circuit. By conducting this study, it can be seen the profile of the overall system operation before and after this interconnection. The simulation results show that the PLTBm connected to the nearest feeder point from the generator is the best choice in terms of making the system voltage better between 19.1 kV and 20.17 kV. Power losses range from 439 kW and 5005.4 Kvar as well as short circuit currents, namely 13.73 KA.
